Green Bank is a census-designated place in Pocahontas County in West Virginia's Potomac Highlands inside the Allegheny Mountain Range. Green Bank is located along WV 28. Green Bank is also close to the Snowshoe Mountain ski resort. As of the 2010 census, its population was 143.
Located within the National Radio Quiet Zone, it is home to the Green Bank Telescope, the world's largest fully steerable radio telescope, which is operated by the National Radio Astronomy Observatory (NRAO). It was at the NRAO, in 1960, that Frank Drake presented the Drake Equation, which was developed to provide an estimate of the total number of detectable extraterrestrial civilizations in the Milky Way galaxy.
With Green Bank being located within the Quiet Zone, many people who believe they suffer from electromagnetic hypersensitivity are finding new homes within its borders. Escape from cellular radiation is the main attraction to Green Bank for these people. As of 2013, an estimated 36 people have moved to Green Bank to escape the effects of electromagnetic hypersensitivity.
